Today, Google has launched a new search statistics service: providing "more flexibility and functionality for advertisers and marketers to understand search behavior". Similar to Google Trends, the new service: Google Insights for Search delivers data on search volume over a period of time, allows you to compare several search terms, and provides regional search statistics. Both services present search volume graphs, but Google Insights for Search also provides regional search volume data in a world "heat map", and gives information on the top related and rising searches for the search terms entered. Not sure why these new features were not just added to Google Trends, but both services offer a lot of valuable data useful for research, targeting and optimization.
